Abstract

The invention discloses monopropellant attitude control engine modules and combinations thereof. The monopropellant attitude control engine modules comprises an engine module, the engine module is provided with a propellant inlet, an electromagnetic valve mounting part, an electromagnetic valve mounting part and a thrust chamber mounting part, and a thrust chamber mounting part; the monopropellant enters the engine module from the propellant inlet and enters a thrust chamber through control of an electromagnetic valve, the propellant makes full contact with a catalyst in the thrust chamber and is combusted, and high-temperature fuel gas is exhausted from the thrust chamber to generate thrust. According to the monopropellant attitude control engine modules and the combinations thereof, the two thrust chambers and the electromagnetic valves are integrated into one module, the two thrust chambers form a certain angle, the requirement that a single thrust chamber is started or the two thrust chambers are started at the same time can be met, and the multiple engine modules and the combination of the multiple engine modules are used in a matched mode so that the requirement for attitude adjustment such as pitching, yawing and rolling can be met for an aircraft.

Description

Technical field: [0001] The present invention relates to the technical field of space vehicles, in particular to a single component attitude control engine module and its combination. Background technique: [0002] Attitude control engines are widely used in rocket upper stages and space vehicles, and are key components for aircraft attitude adjustment. However, the attitude control power system generally has a large number of engines, which has problems such as complex system, many pipelines, cumbersome engine installation, inconvenient maintenance and low reliability. Invention content: [0003] The purpose of the present invention is to provide a single component attitude control engine module and its combination to solve the problem of complex structure of the attitude control power system in the prior art, many pipelines, cumbersome engine installation, inconvenient maintenance and low reliability. question. [0004] Above-mentioned purpose realizes by following tec...
